Java中的Do / While语句

Question

有没有办法像这样制作Do / While语句？

do {
    JOptionPane.showConfirmDialog(null, "Do you wish to continue?");
} while (answer == yes);

Answer 1

而不是answer == yes，您应该检查它是否等于JOptionPane.NO_OPTION或JOptionPane.YES_OPTION。

此外，您应该int answer = JOptionPane.showConfirmDialog(null,"Do you wish to continue?);

Answer 2

您可以将其更改为：

int answer = JOptionPane.YES_OPTION;
do {
    answer = JOptionPane.showConfirmDialog(null, "Do you wish to continue?");
} while (answer == JOptionPane.YES_OPTION);
